A.2 MECHANICAL HAZARDS
The most common mechanical hazards due to a failure to follow the instructions in this user manual
are listed below.
A.2.1 STRUCTURAL RESISTANCE
The structural resistance may be impaired by the following adverse working conditions:
ENVIRONMENTAL TEMPERATURE
- Weakening of the crane structure
- Hydraulic oil viscosity too low/high
- Hydraulic oil overheating
- Weakening of plastic components
- Degradation of flexible hoses (-40°C ÷100°C)
INCLINATION OF THE CRANE'S BASE
- Crane rotation not possible
- Overpressure in slewing cylinders
- Overstress in rack - pinion wheel or thrust block - motor coupling
- Overstress in crane structure
- Loss of stability
INCLINATION OF THE CRANE'S BOOMS
When the crane works with the booms in a near-vertical alignment (lifting moment is near zero), the
load limiting device could operate without the expected accuracy due to:
- oscillations / accelerations of the booms
- inclination of the vehicle
- wind
- joint clearances, frictions
This could cause:
- Overstress in crane structure
- Loss of stability
OIL FLOW RATE TO MAIN CONTROL VALVE
- Overstress in crane's structure caused by excessive speed of movement
- Excessive oil temperature
WIND SPEED
- Overstress in crane structure
- Excessive oscillation of the load
- Loss of stability
PRECIPITATION
- Lightening, electric shock
- General malfunctioning of the electric system
USE IN EXPLOSIVE ENVIRONMENTS
- Flammable hydraulic fluid and plastic components
INSTALLATION ON RIGID BASE
- Excessive forces of inertia
USE IN MARINE ENVIRONMENT
- Corrosion of structural components: cylinder rods, pins, winch rope (offshore cranes)
- Excessive forces due to oscillation/inclination (ship-mounted cranes)

LIFTING COMPONENT
- Excessive forces if lifting components other than hook are used
IP PROTECTION LEVEL
- Electric system faults (safety and controls)
WARNINGS
- Do NOT use the crane if the operating conditions are incompatible with the instructions given in
this manual. Specifically, the user must contact the crane manufacturer if the environmental
temperature is outside the range given in this manual.
- Handling of loads at heights requires full risk assessment: strictly adhere to the load charts and
always fully extend the stabilizers.
- Suspended loads must not be left unsupervised: put the load on a stable place before leaving the
control station.
- Do not slew the crane at max. speed up to the end of stroke (dead point), but approach slowly.
- Clear any snow or ice from the crane booms to prevent excessive stress caused by the extra
weight and to ensure that movement of telescopic components is not affected.
- Contact an authorised assistance centre before using or transporting the crane in a marine
environment.
- The lifting component to which the diagrams refer in this manual is the crane hook. If other lifting
components are used, the user must contact an authorised assistance centre to obtain a
dedicated load chart.
- Maintenance on the machine which requires welding or grinding is forbidden. Refer to an
authorised assistance centre if repairs or modifications to metalwork are required.

A.2.2 CRUSHING HAZARD
Crushing hazards derive from moving components on the crane:
•body crushing between the crane and vehicle
•upper limb crushing between base and crane booms
•body crushing between stabilisers and a stationary object during stabilizer opening
•limb crushing when stabiliser legs are retracted
•lower limb crushing under the stabiliser feet
•limb crushing in openings
WARNINGS
- Cordon off the working area using barriers and warning signs before starting any operations with
the crane. Use special signals to warn others when crane movement is about to start. Avoid
hazardous situations in which the user or other personnel may be crushed by the crane,
stabilizers or the load.
- Do NOT climb on to the crane base when the vehicle's engine is running.
- When handling the crane, avoid grasping the control levers: operate them only with the fingers.
- Keep all personnel away from the hydraulic stabiliser extensions during opening.
- Do NOT place limbs under the stabiliser feet.

USER MANUAL

WARNINGS
A.5
7844058-00 03/20
subject t
o change without notice
- Do NOT place lower limbs between the stabiliser legs and the vehicle. Do NOT place hands near
the stabiliser extensions during retraction.
- Do NOT perform maintenance when the crane is moving or when the power take-off is enabled.
Do NOT touch the crane when it is moving.
- Abide by safety distances indicated in EN 349 and make sure all others do the same.
A.2.3 CUTTING HAZARD
Residual hazard associated with movement of booms and connecting rods. A residual cutting
hazard exists for the upper limbs between moving parts associated with the booms, base and
telescopic components.
WARNINGS
- When the crane is working, do NOT place upper limbs between the boom joints, near connecting
rods or in the area where the stabiliser extensions are retracted into the base. Do NOT insert
fingers, feet or limbs inside openings on moving parts.
- Do NOT stand between the base and booms during crane folding.

A.2.4 IMPACT HAZARD
Residual hazard associated with:
•impact with the crane boom during unfolding/folding
•impact with the moving load
•impact with the stabilisers
•impact caused by an accidental release of the load
WARNINGS
- Take care not to bump against moving parts on the crane. Specifically, do NOT bang your head
on the boom during working operations.
-
- Take great care not to bump against the suspended load. The load must always be moved under
safe conditions away from potential hazards and obstacles, as specified in this manual.
- Always check that the load lifting components (hook, shackle, slings, chains) are in perfect
condition. Do NOT exceed the maximum load indicated on the plate. Check that the load is
properly secured to prevent accidental falling. Do NOT stand under the load.
- If the crane is equipped with turning stabilizers, take care to prevent impact with things and
persons during rotation.
